SQL Query to retrieve records for all after the Max Dates.
Hello everyone,
I am trying to retrieve the record more recent, based on the date field ( nextDate ).
Currently, there are only 4 records in the MC_Maintenance table and two in the Machine table.
Machine table
MC_id EquipID
1 0227
MC_id EquipID
2 0228
---------------------------------
MC_Maintenance table
Maint_id MC_id Next_maint
1 2 08/25/2010
2 2 07/01/2010
3 1 2010-11-06
4 1 07/11/2010
I have am trying to accomplish is,.
the list of the two machines of the table of the Machine with the MAX (Next_maint) control the list of MC_Maintenance results
These are the records I want to display.
Maint_id MC_id Next_maint
1 2 08/25/2010
4 1 07/11/2010
Here is the SQL query
SELECT
MC. MC_ID as ID,
MC.complete_Date completed.
MC.next_maint as nextDate,.
MC.maint_notes as noted,.
MC.facility Facility.
M.EquipId,.
$m.name as the name.
M.SerialNumber SN.
M.dept as dept.
M.Freq as freq
Of MC_Maintenance MC, Machine M
where MC. MC_ID = M.MC_ID
' Using MAX (nextDate)
Any ideas would be useful.
TJ
I thought it was a simple group of problem?
SELECT M.EquipID, MC.MC_ID, Max(MC.next_maint) FROM MC_Maintenance MC INNER JOIN Machine M ON MC.MC_ID = M.MC_ID GROUP BY M.EquipID, MC.MC_ID

Help me on the writing of SQL query to retrieve a single record for each employee of the following table? preferably a standard SQL.
CREATE TABLE xxc_contact)

alternatecontact VARCHAR2 (100),
relationship VARCHAR2 (10),

Phone NUMBER
);
insert into xxc_contact values (123456, 'Rick Grimes', 'SP', 'Cell', 9999999999)
insert into xxc_contact values (123456, 'Rick Grimes', 'SP', 'Work', 8888888888)
insert into xxc_contact values (123457, 'Daryl Dixon', 'EN', 'Work', 7777777777)

Specifically, the two simple solutions provided were:
1 using the row_number, entitled Oracle ranking based on descending order of the inside telephone each empnum group. And finally selects the lines which has least rank (of least since that order is descending for phone).
SQL > column alternatecontact format A20;
SQL >
SQL > SELECT empnum, alternatecontact, relationship, phtype, phone
2 from (SELECT a.*, row_number() over r (PARTITION BY empnum ORDER BY phone / / DESC))
3 FROM xxc_contact one)
4. WHEN r = 1

EMPNUM ALTERNATECONTACT RELATIONSHIP PHTYPE PHONE

2. with the help of MAX, Oracle automatically assigns the maximum phone for all the rows in each group of empnum. And finally selects the rows with the maximum phone. Order by clause is omitted here intentionally. You can find out why.
SQL > SELECT empnum, alternatecontact, relationship, phtype, phone
2 (SELECT a.*, MAX (phone) over (PARTITION BY empnum) rn FROM xxc_contact one)
3 WHERE phone = rn
4.
EMPNUM ALTERNATECONTACT RELATIONSHIP PHTYPE PHONE

Vista goes to 50% CPU usage and connects the computer for hours after the beginning
Original title: Vista processor
Stupid Vista goes to 50% CPU usage and connects the computer for hours after the start. Cannot run anything with any request of CPU without getting bogged down and crashing. It is not windows defender, I suspend this service and the machine is ok for another 1/2 hour, them I'm up to 50% of the CPU. The idle process said Task Manager is > 90%, still indicates 50% CPU usage and the cooling fan looks like a 747 taking off. Should I just pull the machine and go for Linux, or what? Cannot run games or whatever it is, totally disgusted with vista of POS and microsoft can it Deep and do not get windows 7, it is probably worse. Is that all I can turn off to get the same performance than, say, windows 3.1? It would be preferable to the current situation. MSCKMA.

For each driver in the list, additional useful information is displayed: load address of the driver,

Control Panel - device - Graphics Manager - note the brand and complete model
your video card - double - tab of the driver - write version information. Now, click on update

Uninstall - REBOOT it will refresh the driver stack.Repeat this for network - card (NIC), Wifi network, sound, mouse, and keyboard if 3rd party
with their own software and drivers and all other main drivers that you have.Now in the system manufacturer (Dell, HP, Toshiba as examples) site (in a restaurant), peripheral
Site of the manufacturer (Realtek, Intel, Nvidia, ATI, for example) and get their latest versions. (Look for
BIOS, Chipset and software updates on the site of the manufacturer of the system here.)Download - SAVE - go to where you put them - right click - RUN AD ADMIN - REBOOT after
each installation.Always check in the Device Manager - drivers tab to be sure the version you actually install
presents itself. This is because some restore drivers before the most recent is installed (sound card drivers
in particular that) so to install a driver - reboot - check that it is installed and repeat as
necessary.Repeat to the manufacturers - BTW in the DO NOT RUN THEIR SCANNER device - check

Buy unlocked iPhone 7 right after the release date
Friends good day! Let's say I want to buy an iPhone 7 right after the release date before apple officially begins selling the devices free SIM card. I'd be able to come simply to store and buy, for example, an AT & T phone to use with my operator? Because I know that they would be not selling sim free phones in the first two weeks. Or do I have to buy a plan as well and become a customer of AT & T? In other words, I need now a unlocked device, and can I get one without waiting for the start of the free features of SIM card sale. Thank you!
If you buy any iPhone outright directly from Apple full paying, it is carrier unlocked.
